u This invention f relates :tov af-v dumping-scow `havingl port and starboard pocket'shinged-and locked to a centrally located bridge, with bow and stern pontoons xedat the ends, thus the bridge and perpendicular lpontoons in -plan` form an `H, lprovidingtwo recesses for housingv the pockets.v

The primary object of the invention-is yto provide a self-dumping, automaticclosing, `dumping-scow for transporting mudandother heavy material to sea, or other disposal area.

Loaded pockets `are released simultaneously and will pivot downwardly under water from horizontal to vertical positionsldischarging `the `material to both sides aided by gravity, and the inrush of water scours` the pockets. When water has become static, the deck of the pontoons and the bridge riseabove the surfaceof the watergland the pockets pivot upwardly against gravity, Adueto the yair-compartments `built into the outer walls of the sloping sides of the pockets, returning and locking themselves into their original horizontalE positions.- While pivoting upward the pocketsfpe'rform 'outward scoopingmotions, that-tendto eject'the water from said pockets. i f f Other objects of the invention will become apparent fromm `the following specification, the drawings and from the claims." f

1n the drawings: V i

Fig. 1 is a perspective drawing, showing the parts comprising the bow and stern pontoons xed to the bridge fore and aft, and the port and starboard pockets. Broken l.away area shows section below deck. r I Fig..2 shows a perspective drawing of theforward part of the bridge deck-.with a part broken away toshow the apparatus for lockingthe pockets. l

Fig. 3 is a side elevation of the forward end of the scow with the port side pocket in a dumping vertical position.

Fig. 4 is a transverse vertical section taken at line 4-4 of Fig. 1 showing pockets in vertical dumping positions.

Fig. 5 is a transverse vertical section taken at line 4-4 showing pockets in horizontal, closed positions.

Similar numerals refer to similar parts throughout the specications and drawings.

In Figure 1, the component parts of the scow show bow pontoon I0 and stern pontoon I I, xed to the ends of the centrally located longitudinal bridge I2; with the port side pocket I3 and the starboard Pocket I4 hinged to the lower sides of 9 claims. (o1. 114-29) the bridge walls 36 and 3`I, at I5 and I5, in line with the bottom wall 3I. The bridge I2, and the perpendicularly fixed pontoons I0 and II in plan form an H, which provides the two recesses wherein the pockets I3 and I4 are housed, and locked when empty, and before loading the scow.

The said pockets I3 and I4 have only top-side openings for Ioading, or depositing the material therein; and from which the material is subsequently discharged by drawing bolt 2 I, which releases the catches I9 lshown in Figure 2 and that allows the pockets I3 and I4 to pivot Von hinges I5 and IE` from horizontal to vertical positions as shown in Figures 5 to 4, taken at line 2-2 of Figure A-1. Thebottom walls of the pontoons Iii and II, and the bottom walls of the pockets I3 and I4, shall be at the same plane, but the bottom wall 3I of the bridgeV I2, must be above the bottom walls of the pockets 23 and 24 as shown in Figure 5, a difference equal to one half the width of the bottom 3| of the-bridge, or vice versa, the bottom wall of the bridge 3i must be at least twice Vthe difference between Vthe bottom wall of the bridge 3I and the bot- 25 tom walls of the 'pockets 23 and 24, in order that when the pockets I3 and I4 as shown in Figure 5 are to be dumped the pockets may pivot downwardly, and the bottoms l23 and 24 of said pockets can tilt under the bridge and meet in vertical positions as shown in`Figure 4, thus permitting the material to be discharged by gravity, `aided by the inrush of water yinto the pockets I3 and I4, which also scours` the pockets of any material, `before the buoyancy of the air-compartments contained in the outer walls 25 and I6 of the pockets I3 and I4pivot upwardlyiromvertical tofhorizontal` positions against gravity; while in `so doing, both pockets perform scooping'motions ejecting the water within the pockets to both sides, as the scow rises on the surface of the Water. When the cycle of the various actions have been completed, the scrow when empty will again assume the status as before loading, or while being loaded, as shown in Figure 1 and Figure 5.

In .Figure 1, are shown three bulkheads 29 in each pocket making four compartments, there may however be more or less number of compartments and bulkheads 29, depending upon the length of the scow and the pockets I3 and I4. These bulkheads tend to brace and reenforce the pockets I3 and I4, when the scow is loaded. and while in transit.

The scow should be built of metal, prefer-- y e 3 -ably of alloy steel sheets and structural shapes, that are non-corrosive, or nearly so.

Y The sloping inner sides 21 and 28 of the outer scow, another locking arrangement may be used, if found to be of better advantage; the main object of this invention being to provide a dumping-scow that can be more conveniently operated, to save time and labor with less maintenance.
